WASHINGTON, DC (WUSA9)-- In this week's Food Alert, a fine dining restaurant operating with an expired business license, another without a health permit, and then there are the mold and rodent issues.

Health inspectors shut down Taipei 101 Tokyo Cafe on Bethesda Avenue in Bethesda, MD;  Mauricio's on Bladensburg Road in Brentwood, MD;  Cups and Mugs located in the Reston Hospital Center in Fairfax, VA; ZMart on South Capitol Street in Southwest, DC; and, Rajaji Curry House in Northwest, DC.

At Bethesda's Taipei 101 Tokyo Cafe inspectors observed, "Rodent droppings throughout the facility and on food contact surfaces."

At Cups and Mugs in Fairfax, county health inspectors closed the coffee shop citing "critical health code violations."  Inspectors wrote-up the shop for not staffing anyone certified in food safety, not tracking workers' disease status, and not having required soap and paper towels.

KING GEORGE, Va. (WUSA9) -- US Senator from Virginia is demanding answers after another medical mix-up at Walter Reed Military Medical Center.

Mark Warner wants to know why a Virginia woman was sent home with a powerful and potentially deadly heart drug -- instead of the vitamin shots she was supposed to get.

Christiane Wiggins was shaken when her son opened the package of medicine dispensed from a Walter Reed clinic at Dahlgren Navy Base. "My brain went. I was sick to my stomach," says Wiggins. 

"It was labeled B-12 on the bag, labeled as B-12 on the package insert, on the printed label on the bottle," says her son Chris.

But when he pulled out the vials, what he found inside was atropine, a potent drug used to help resuscitate heart patients. "And he said 'Mom, if I gave you this injection, it might kill you,'" remembers Wiggins.
